Eric Dumazet fe30937b65 bonding: fix bond_get_stats() ... bond_get_stats() can be called from rtnetlink (with RTNL held) or from /proc/net/dev seq handler (with RCU held) The logic added in commit 5f0c5f73e5 ("bonding: make global bonding stats more reliable") kind of assumed only one cpu could run there. If multiple threads are reading /proc/net/dev, stats can be really messed up after a while. A second problem is that some fields are 32bit, so we need to properly handle the wrap around problem. Given that RTNL is not always held, we need to use bond_for_each_slave_rcu().
